Answer:
x = 5 , y = 5
Step-by-step explanation:
Using the sine and cosine ratios in the right triangle and exact values.
sin30° = , cos30° = , then
sin30°= = = ( cross- multiply )
2x = 10 ( divide both sides by 2 )
x = 5
and
cos30° = = = ( cross- multiply )
2y = 10 ( divide both sides by 2 )
y = 5
Answer:
The population of interest to the researcher were the 250 first-year students that were monitored.
Step-by-step explanation:
In descriptive statistics, the portion of the cost of college education to be determined and has been selected for analysis is calle
d "sample", the sample the researcher is interested in, considers the textbooks cost of first-year students, therefore the 250 first-year students is the researcher´s population of interest. This method involved the collection, presentation, and characterization.
Answer:
b and c
Step-by-step explanation:
The Triangle Inequality Theorem lets us know that the sum of the two shortest sides of the triangle must be greater than the third side of the triangle.
In both A and D, the sum of the shortest two sides are equal to, not greater than the third side, so they will not form a triangle.
In B, 12+20 is 32, which is greater than 25. And in C, 18+24 is 42, which is greater than 30, so they both will form a triangle.
Answer is 553 beasts
Step by step:
Multiply 158 by 3 to get 474
Divide 158 by 2 to get 79
Add 474 with 79 and get 553
